Charging and Installing Batteries
The Sensor is powered by four AA-size batteries (1.2~ 1.5V). You may use the four AA-size
1.2V NiMH batteries provided with the Sensor, or you may use AA-size alkaline batteries
(1.5V). Before using your Sensor, make sure the batteries are fully charged.
The Sensor is reverse voltage protected: installing batteries backwards cannot damage it. I f
the batteries are backwards, simply reverse the battery connector.
Also inside the battery compartment is the 4 wire Receiver Programming Cable. This cable
can be plugged into the receiver’s TACH pins in order to upgrade the software on the receiver.
The RC Desktop will instruct you when a software upgrade is available.
Charging the Supplied NiMH Batteries
When using the supplied NiMH batteries, charge the batteries for 12-14 hours (using the
supplied charger) before using the Sensor. Be sure to get the polarity correct when installing
the batteries into the charger.
